Hello,

I'm using GIMP to create a raster image and I want to know if is possible to do the same thing in InkScape to create a vector image. Here is what I do in GIMP.

1) First I draw a bunch of lines with the pencil or brush.

2) Then a Gaussian blur is applied to the entire image.

3)The warp tool is used to to create like a whirl of color with parameters: hardness - 0, strength - 100 and abbys - loop

4)Finally sharpness filter is applied to the entire image.

This images show and summarize the process:

Freehand draw bunch of lines

Apply blur to the entire image

Use the Warp tool and swirl the colors

Apply sharpness

Hi,

no, not really. 

Assuming you want this as vector as to be able to scale it up large, there is only the gradient mesh tool that can create such fancy gradient transitions. 

But even that's not really vector, you'd have problems saving it as eps. 

Theoretically inkscape filters may be capable of rendering a similar distortion as the warp tool so that later you can render in a larger resolution.

However inkscape's filter rendering is quite limited (you'd end up with something a bit chunky, with not-so-smooth transitions) and that task would still be very complicated 

AND raster image based. 

(It'd require a raster image as an input for the displacement filter primitive. Something similar is presented here:

Thanks.

I found this tutorial on youtube but it lacks... how can I say... the "smokiness" 🤔 in the blend transitions and the curves doesn't end in a sharp point like the way it can be done in GIMP. I was already told that trying to "vectorize" in InkScape, the image created in GIMP, is not possible either, is that correct?

Sorry forgot to include the link to the tutorial in youtube here it is:

Inkscape has an option to vectorise n image >see trace bitmap in the manual-

That will generate flat filled layers of colours based on the lightness levels mostly. Process is very slow, can produce 256 "layers". 

If that's a greyscale image, it could work "smoothly" yet there are still limitations. 

Illustrator has a different approach on vectorizing raster iamges, building it up from smaller chunks, producing some more "fluent" results but it won't be crystal clear either. 

You will lose details. 

It is a challenge to produce such imagery, however not completely impossible to do so with the mentioned gradient meshes. 

Takes long time to do so, there is no one click solution here.

Here is the link to the youtube video because I tried to use the "Embed Youtube Video" option twice but didn't work:
